APPARATUS FOR TAKING PROOF.

SPECIFICATION forming part of Letters Patent No. 278,848, dated J'une 5,1883. Application filed January 22, 1883. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. BALDWIN, a citizen of the United Statesof North America, and a resident of the city, county, and State of NewYork, have invented a new and useful Improvement in Apparatus for TakingProof, of which the following is a specification.

The object of this invention is to savetimeand labor in taking prooffrom type forms by providing a portable device for that purpose.

The invention consists of a device composed of two rollers of unlikecharacters and func tions, held apart and parallel to each other by aportable handle or frame, so that each one is capable of independentrevolution. One of said rollers is an inking-roller, composed of orcovered with the composition ordinarily used for printersinking-rollers, and the other roller is designed for'pressing theproof-sheet upon the form, and is constructed preferably of metalcovered with felt or other suitable elastic material.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan of my improved device. Fig. 2 is an end elevation ofthe same. Fig. 3 is a sectional end elevation of the same 011 line at00, Fig. 1.

In the drawings, A represents the frame of the device, consisting of aspindle, a, having secured on each end and in line therewith a handle,I) 0, provided with a rose or plate, 0 c, as shown. On one side of thespindle a a cylinder, B, preferably of metal, covered with a sleeve orcovering, (Z, of felt or other elastic material, is held so that it mayrevolve by spindles f f, that journal it in the opposite roses or plates0 c. On the opposite side of the spindle a a cylinder, 0, covered withordinary inking-roller composition, 9, is j ournaled, so as to revolveparallel with the cylinder B between the roses or plates 0 c, byspindles h h. Projecting downward from the roses or plates 0 c are feetkk, that serve to support the device in an upright position when not inuse, as shown in Figs. 2 and 3.

When it is desired to take proof by means of this device the cylinder orroller 0 is inked in the usual manner and then run over the form, theoperator taking hold of the handles 1) b and applying the roller O withsuitable pressure for properly inking the type. Then.

the sheet on which proof is to be taken is laid upon the form, and thepressing roller or cylinder B is run over the back of said sheet by theoperator, a very moderate pressure sufficing to insure perfect prooffi.

WVith this device proof can be taken on the standing-rack or stone, andmuch time be thereby saved in going to and from the proofpress and byits use a small order of circulars, cards, &c., can be printed withoutthe trouble of locking upa form and making ready on a press. With this,too, dead matter can be proofed in any position in which it may bestanding, and any inside matter of any size of form can also be proofedwithout the use of a covered planer and mallet, as is now the case.Turtles and circular forms, now used in rotary presses, can be proofedwith this device as easily as flat forms can be. There are numerousother uses to which the device can be advantageously applied, which willreadily occur to the mind .of any practical printer.

I do not confine myself to the construction of the device precisely asherein shown and described, for the feet It is may be dispensed with anda separate independent holder or support be provided, and the form ofthe handle or frame may be modified without departing from my invention.

Having thus described my invention, claim as new and desire to secure byLetters Patent- 1. As a new article of manufacture, an apparatus fortaking proof, constructed.- substantially as herein shown and described,consisting of an inking-roller and an elastic pressingroller, held in aportable handle or frame apart and parallel with each other, so as to befree to revolve independently of each other, as set forth.

2. The combination, with the portable frame A, provided with the legs isk, of the pressing cylinder or roller B and inking cylinder or roller 0,all arranged and adapted to operate substantially as herein shown anddescribed.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 12th day of January, 1883.

CHARLES E. BALDWIN.
